CSSE 220 – Object-Oriented Software Development

Homework 8

Objectives

Practice with arrays and ArrayLists in Java. More practice with loops and debugging in Java. More practice implementing classes based on a given specification.

Tasks

1. Complete the assigned reading for today's session (Session 8: Big Java, §7.1–7.6), according to the course schedule.
   • As you read, see if you can answer the self-check questions.
   • Bring your questions to next class!
2. Complete the assessment exercise over this reading on ANGEL (under Lessons → Assignments).
3. Programming:

   1. In Eclipse, checkout the ArraysAndLists project.

      • Note: you might find the first 8 items from the summary on arrays and ArrayList's helpful for this exercise.

   2. With your instructor, discuss the specification and complete the design for the RollingDice program.

      Implement the TODOs in RollingDice in order.

   3. ArrayList practice:
      1. We have created documented stubs of a constructor and several methods in the QuizScores class. Implement these documented stubs, testing each using the JUnit 4 tests supplied in QuizScoresTest.

         Note the implementation requirements for the QuizScores exercise:

         • Use an ArrayList<Integer> to store the scores.
         • Use the enhanced for loop where practical.
         • Do NOT use methods from Arrays or Collections in the QuizScores class.

         Big Java, §7.6 (7.5 in ed3), may be a helpful reference if you get stuck, as might the summary on arrays and ArrayList's.
